Calcium aluminate cement is a kind of monolithic refractory material that has a long history in the constructing of high temperature furnaces, kilns, stoves, incinerators, etc. China has a great amount of calcium aluminate cement manufacturers, who provide abundant calcium aluminate cement every day. The main raw material of the cement is aluminate oxide, which has a very high melting temperature and a good refractoriness.
The cement is used in various industries such as petrochemical industry, power industry, iron and steel industry, ceramic industry where high temperature materials are required.
High alumina cement is a kind of hydraulic material, which means, it can be hardened with water under normal temperature. This is very environmental friendly since the procedure ask for no heating up. And the heating up process usually concerns about coal burning. .
One of the biggest advantage of calcium alumina cement is that it can be molded freely and have a high mechanical strength after hardened. This is amazing because the material can invade into any kind of cracks on the wall of the building, fill in the cracks and make it a whole again. The cement also have a very good high temperature performance, which means, it shows the excellent properties under high temperature as good as it does in normal temperature. These high temperature performances include corrosion resistance, erosion resistance, high refractoriness under load, high hardness, and high mechanical strength.
High aluminate cement is usually used to bind high alumina bricks together. Its mechanical strength and air tightness is a good nature to help build a tight wall and prolong the service life of the furnace.
Another usage of high aluminate cement is to mix it with refractory aggregates to make refractory concrete. The concrete can be casted to build monolithic building structures.
